PRIMER AND AIR INTAKE ron GAS ENGINES.

Application filed Marchfi, 1323. SerialNfo. 623,130.

To all whom it may concern;

Be it known-thatl, LARKIN J. SKINNER, a citizen o f the United States,residingat F letcher. in the county of Comanche and State of Oklahoma,'l aveinvented certain new and useful Improvements in PrimersandAirInt-akes for Gas Engines, of which the following is aspecification.

My invention relates to a combination primer and airinlet for gasolineengines primarily. but not specifically, adapted for use in conjunction;withthe engines of Ford automobiles whereby-a charge of gasoline may betaken into the engine manifold whenever desirable, and the inventionbeing adapted for permitting. a supply of hot air to also enter themanifold while the engine i running for assisting in a thorough vaporization of gasoline.

A further object of my invention resides in the'provision of a device asis comparatively simple in construction of such a nature as to beexpeditiously adapted for application to Ford engines to be held inplace by th elements which hold the intake and exhaust pipes in place.

l/Vith the above and other objects in view as the nature of theinvention is better understood upon consideration of. the followingspecification and accompanying drawings the same consists in thecombination and arrangement of parts hereinafter more fully described.

In the drawings, wherein like reference characters indicatecorresponding parts throughout the several views:

Figure 1 is a side elevational view with a portion of the motor of aFord automobile together with my improved primer and air intake;

Fig. 2 is a vertical cross sectional View taken substantially on theline 22 of Figure 1;

Fig. 3 is a fragmentary vertical cross sectional view of the engineintake manifold showing more clearly the type of three-way valveemployed in conjunction with my invention; and i Fig. 4 is a transversecross section of the gasoline storage tank for disclosing more clearlythe supporting means therefor.

Referring to the drawings in detail, 5 designates an exhaust manifold ofa Ford type motor; 6 the intake manifold; 7 the carburetor; andS thevehicle dash board,

all of these parts being'of well known construction and therefore not"the essence of my invention, the same beingshown so as to moreadequately disclose the relation of my invention therewith.

My invention embodies the provision of gasoline supply tank 9 ofanvdesirable capacity. the same being rigidly secured upon the said vehicledash 8 through the instrumentality of a strap 10, the ends of the strapbeing formedwith brackets 11 as more clearly shown in Figure 4.These'brackets 11 are secured to the dash by any appropriate fasteningmeans 12 such as screws or the like; i i i Positioned upon the exhaustmanifold 5 is'what may be termed a hood 13, this hood being rigidlysecured upon the manifold through the mediumof the usual clamping arms14 between the exhaust and intake manifolds. This hood 13 is in the formof a metal plate, the upper end thereof being curved to conform to thecurvature of the manifold 5 as more clearly shown in Figure 2. The edgesof the hood 13 are flanged inwardly as at 15 whereby the said hoodsupported in spaced relation to the manifold. a

In the practical application of my device to an automobile engine of theFord type the manifold 6 is provided with a screwthreaded opening 16 anddisposed within this opening is the screw-threaded nipple 17 of athree-way valve 18. As clearly shown in Figure 3, the nipple 17 formsthe outletfor this valve while the same is further provided with a pairof inlets 19 and.

20, the same being screw-threaded as shown. Secured to the inlet 20 ofthis valve 18 through the instrumentality of a coupling 21 at one end ofa gasoline feed pipe 22 the same extending upwardly and being in turnsecured to an outlet valve 9 of the said gasoline storage tank 9.Secured in a similar manner the other inlet nipple 19 to the said valve18 is one end of a hot air pipe 23, the same being in directcommunication at its opposite end with the said hood 13 upon the intakemanifold 5. The valve core 18 carries the usual operating finger piece 21 and loosely and pivotally secured to this finger piece 24 is one endof an actuating rod 25, the same extending rearwardly as shown and beingengaged through an opening 26 of the dash board 8, the end of this rodbeing formed in an operating head 27 whereby said rod 25 may berotated.

In view of the above description it will at once be apparent that whenthe valve core 18' of the valve 18 is in-a position as shown in Figure 3and the motor is running hot air will be sucked into the manifold 6assisting in the thorough combustion of the fuel. In starting a motor incold weather it is desired to inject a charge of gasoline into themanifold, the valve core 18 is turned so as to establish communicationbetween the gasoline feed line 22 and the said outlet nipple 17 of thevalve, it being further understood that if it is ever found desirablethe valve core may be rotated to sucha position as to permit a partialcharge of air together with a small charge of fuel pass into the intakemanifold 6.

Although I have'shown and described the preferred embodiment of myinvention it is nevertheless to be understoodthat minor changes may bemade therein Without departing from the spirit and scope of the inVention as claimed.

, Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

An explosive engine starter comprising a tank independent of the tankwhich is normally employed for supplying liquid fluid to the engine, avalve body applied to the intake manifold of the engine at a pointbetween the point of connection of the said intake, manifold with thecarburetor and the branches of the said manifold, a pipe for conductingpreheated air from the exterior of the exhaust manifold of the'engine ata point between the ends thereof and connected with valve bodies, a pipeconnected with the first mentioned tank and with the saidvalve body, avalve turnably mounted in the valve body and means for turning thevalve, the parts being so arranged that the heated air and fuel from thefirst mentioned tank may be admitted in a mixed condition into theintake manifold and in advance of the mixture which is lead into thesaid manifold from the said carburetor.

In testimony whereof I afiix my signature.

LARKIN J. SKINNER.
